ALEXANDER LAUGHLIN, OF SEWIGKLEY, PENNSYLVANIA.

GAS-PRODUCER.

SPECIFICATION forming part of Letters Patent N 0. 676,329, dated June 11, 1901. Application filed August 15, 1900. Serial No. 261982. (No model.)

- To 0052 whom it may concern:

. Be it known that LALEXANDERLAUGHLIN, of Sewickley, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Gas-Pro ducers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to gas-producers,and

has special reference to the blast-supply.

The primary object is to increase the efficiency and expedite the operation of the producer. This I accomplish by thoroughly heating the. air before it is blown into the producer.

A further object is to provide simple and highly-efficient means for effectively heating the air before its passage into the blast-pipe.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 shows in elevation a producer equipped with my present improvements. Fig. 2 is a horizontal sectional view of the producer-body on line 2 2, Fig. 1. Fig. 3 is a vertical section on line 3 3, Fig. 1. Fig. 4 is'a horizontal sectional view on line 4.- 4, Fig. 1.

Referring to the drawings, 1 designates the body of the producer, 2 the ash-hopper, and 3 the pit for forming a water seal around the ash-hopper, features which may be of ordinary or preferred form of construction.

Around the body of the producer I arrange spaced-apart air-fines 4, preferably upright, with inlet-openings 5 at or near their lower ends. Some of'these upright air-fines are longer than the others, the poke-openings 6 making it necessary to shorten those flues beneath which they are located. At their upper ends the several air-flues open intoa com- The blast-pipe is shown as discharging at its lower end into a conduit 10 of a blast-distributor 11; but any other means may be employed for the distribution of the blast into themass of fuel in the body of the producer.

The advantages of the present improvement are apparent to those skilled in the art.

'opening'at their upper ends into said chamber and having air-inlets at their lower ends, a blast-conduit opening into the producer at or near the bottom thereof, means connecting said air-chamber and conduit, and means for entraining the air from said chamber to said conduit, as set forth.

2. The combination in a gas-producer of the following instrumentalities: a body, an encircling air-chamber formed inv the wall of said body, a series of fines, also formed in said body, opening at their upper ends into said chamber and having air-inlets at their lower ends, a blast-conduit opening into the producer at or near the bottom thereof, a blastpipe connecting said air-chamber to said blastconduit, and means for entraining the air from said chamber through said pipe and conduit, substantially as set forth.

3. The combination in a gas-producer of the following instrumentalities: a body, an encircling air-chamber formed in the wall of said body, a series of fines, also formed in said'body, opening at their upper ends into said chamber and having air-inlets at their lower ends, a blast-conduit opening into the producer at or near the bottom thereof, a blast-pipe connecting said air-chamber to said blast-conduit, and a steam-inlet pipe opening into said blast-pipe for entraining the air from said chamber into such pipe, substantially as set forth.

In testimony whereof I have signedthis specification in the presence of two subscribing witnesses.

ALEXANDER LAUGHLIN.
